Although we already knew it had some serious potential, AnandTech has pitted the Viewsonic G (running nVidia's hot Tegra 2 dual-core mobile CPU) against a bevy of other mobile CPUs. The competition: three devices utilizing the Snapdragon (Nexus One, G2, and EVO), the Hummingbird found in the Galaxy Tab, the TI OMAP found in the Droid 2, and the Apple A4 from the iPhone 4. The results: the Viewsonic G tablet and its Tegra 2 CPU pulled heavy wins in 4 out of the 6 tests.

The CPU benchmark results were quite impressive, with results ranging from 30-100% better than the competition in all but Linpack, where the tablet hit 37.324 MFLOPS versus the 38.122 of the Nexus One. Also noteworthy: they point out that not all their tests were multithreaded, meaning that extra core in the Tegra 2 went unused. That's to be expected with tech that has yet to hit the streets, let alone be widely adopted - developers haven't had time (or found the need) to write code that can take advantage of both cores, and it will likely take a few years for that transition to really kick in.

They then ran the Viewsonic G and Galaxy Tab through two gaming tests and found the results to be split. Running two tests is hardly scientific, and each winning one is hardly conclusive, but it looks like that's about all we're going to get for now.

You know, i'm really happy with these benchmarks. I bought an Archos 70 for review purposes, and have had nothing but trouble with it.. starting to think i should of bought this thing!

This doesn't look too good for the Nexus S.

Persumably, it's using the same Samsung Hummingbird CPU like the galaxy S. And according to this review, the Hummingbird is doing worse than the Nexus One's Snapdragon.

Could this be a step backwards with the nexus S or is this simply proof that Samsung software is rubbish to the extent of crippling their superior CPU?

As far as I know, the Cortex A8 is a little bit slower than the Snapdragon. The big difference comes from the optimizations in the JIT Compiler. I'm not 100% sure, but it isn't yet fully optimized for the Hummingbird.

Plus: CPU is one thing, the other thing is GPU. And if you compare the GPU with the Adreno in the Nexus One...well the difference is huge (Adreno is 2-4 times slower).

after looking the way the Google Nexus One performes with an old Snapdragon QSD8250, one can only wish there where a Google Nexus TAB :D that would be a mayor win... because clearly the hardware is worthless without proper software optimization.. so, you should update this charts as soon as the google nexus S comes out.

Rooted, it would rock the socks out of anything here. Then they'd have to compare all of them rooted, and things would get complicated.

It's pretty sad how incompetently the software on some of these products is done - in the end, consumers suffer. That's the beauty of open source - you benefit from the minds of the masses anywhere in the world, the best of the best, and nobody pays them a dime. It's pretty awesome and sad at the same time.

These results make no sense. How can a 1 year old nexus one outperform the G2 almost every test? The G2 is a next generation Snapdragon, it's supposed to outperform the First generation snapdragon easily. Same with Samsung's Hummingbird, it's comparable to the 1st snapdragon but kills it in gpu. And as much as I loathe iPhone 4, how do you figure it's the slowest device in the 1st benchmark at the very top?

The iphone4 has essentially the same hardware as the GalaxyS except with a weaker GPU and a under-clocked processor.
